相似三角形 meaning in Chinese

homothetic triangle
similarity #similar triangles

Let's consider the sawtooth pattern of similar triangles in fig. 9 .
我们来研究图9中一组相似三角形的锯齿形模型。
Compared with the ordinary optimization algorithm of calibration , this algorithm is simple , less computational and high accuracy . finally , the paper put forward the ranging method based on similar triangle principle . it gives two ranging models according cooperation object vertical in the optical axis or not vertical in the optical axis and does experiment
最后,本文提出了一种基于相似三角形原理的测距方法,根据合作目标与摄像机主光轴垂直与不垂直两种情况,给出了两种测距模型,建立实验系统并进行了实验,通过近距离段与远距离段的测距结果与误差分析验证了此方法的有效性,能够准确的确定合作目标的位置,计算简单,测量精度高,具有重要的理论意义和工程使用价值。
